Differential Effects of D 600 on Contractile Response of Aorta and Portal Vein from Spontaneously Hypertensive Rats
Bibliographic record
Abstract
To examine if Ca handling by vascular smooth muscles is altered in hypertension, the in vitro effect of D 600 was determined on noradrenaline-induced contractions of aortic and portal vein strips from spontaneously hypertensive rats (SHR) and Wistar Kyoto normotensive rats (WKY). In low (0.2 and 0.4 mM) Ca solutions, D 600 reduced the response to noradrenaline to a greater extent in aortic strips from SHR than in strips from WKY. In contrast, D 600 had less effect on the response to noradrenaline in portal vein strips from SHR than in strips from WKY in both normal and low Ca. Thus, portal veins from SHR are less dependent on external Ca compared to portal veins from WKY whereas aortae from SHR are more dependent on external Ca compared to aortae from WKY.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
